That ratio on a naturally aspirated K24 is where the power is, so this is a set for a built NA engine, not a boosted one.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eManley's Platinum Series uses domestic 2618 alloy forgings for high-temperature strength and fatigue resistance. Contour forgings balance strength against weight with no grain-interrupting internal milling. The proprietary multi-step top ring groove machining controls groove size, geometry, flatness, and finish, and perfect ring groove to skirt squareness comes from a single-fixturing manufacturing method — better ring seal, more power.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCam and barrel skirt profiles are proven designs for stable rock-free operation in the bore. At 339 grams each, they're genuinely light for a 2618 forging.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e 87mm standard bore, 1.181\" compression height, flat top with -1.0cc volume, 22mm wrist pin.
